Abstract
The utility model discloses a device for detecting excavated earth volume of a shield tunneling machine. The device comprises a displacement sensor, a processor, a shield tunneling machine PLC (programmable logic controller), an operation display and a ground monitoring system, signals obtained by the displacement sensor are processed by the processor and then transmitted to the shield tunneling machine PLC for comparing with set theoretical excavated earth volume, and comparison results are output to the operation display and the ground monitoring system. The device for detecting the excavated earth volume of the shield tunneling machine has the advantages that by detecting excavated earth volume through the displacement sensor and by jointly displaying an actual value and a theoretical excavated earth value after processing and prompting, detection and management are facilitated, so that ground settlement caused by excessive excavated earth is prevented.
Description
Technical field
The utility model relates to the unearthed amount detecting device in constructing tunnel device technique field, particularly a kind of shield machine.
Background technology
Shield machine is widely used in the metro construction engineering, in construction, is transported to the outside, tunnel after the cutterhead by shield machine is lower with the dregs cutting.If the amount of being unearthed will cause surface settlement and depression greater than excavated volume, citizens' activities are brought huge potential safety hazard, the road surface that each metropolis subway construction causes subsides, and to gulp down the car phenomenon also more and more.Therefore, for accurate measurement and the control that reality is unearthed and is measured, be a problem demanding prompt solution, and also be not used for now the equipment of the unearthed amount of special measurement of this construction environment both at home and abroad.
The utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of shield machine amount detecting device that is unearthed, the amount of being unearthed is detected and controls.
The technical solution adopted in the utility model is such: a kind of shield machine amount detecting device that is unearthed, comprise displacement transducer, processor, shield machine PLC, operating display and ground monitoring system, the signal that described displacement transducer obtains is processed to be transferred to afterwards in shield machine PLC through processor and is compared with the theory of the setting amount of being unearthed, and then comparing result is outputed to operating display and ground monitoring system.
Some basic parameters of described displacement transducer: Δ θ is the minimum unit that scans angle; Conveyor shape when Hi is not unearthed; Hm is the height that has when unearthed; V is the Belt Conveying motor speed, and t is the time interval of scanning.
For the selection of concrete scanning element, consider when initial and when unearthed belt have saggingly, therefore choose and sink the roller bearing part less as scanning element.
The signal that obtains for displacement transducer is further processed in processor.Δ H is the mound height, and Δ H is Hm-Hi.Then, obtain section area f(s after the measurement result merging with each minimum unit).Then, use formula
Calculate unearthed volume.
The unearthed amount result of calculating is presented on operating display.Be presented at together with the amount result of being unearthed and also have the predefined theory amount of being unearthed on display screen, with this as a comparison.When the reality amount of being unearthed surpass the theoretical amount of being unearthed 5% the time, operating display will send alarm.
As preferably, described displacement transducer is the laser scanning displacement transducer.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: by displacement transducer, the volume that is unearthed is detected, by after processing, actual value and the theoretical value of being unearthed being shown and make prompting jointly, the convenient detection and management, thus prevent from causing because of excessive being unearthed sinking of ground.
Description of drawings
Fig. 1 is operating principle block diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment: as shown in Figure 1, a kind of shield machine amount detecting device that is unearthed, comprise displacement transducer, processor, shield machine PLC, operating display and ground monitoring system, the signal that described displacement transducer obtains is processed to be transferred to afterwards in shield machine PLC through processor and is compared with the theory of the setting amount of being unearthed, and then comparing result is outputed to operating display and ground monitoring system.
Described displacement transducer is the laser scanning displacement transducer.
In the present embodiment, selected laser scanning displacement transducer can accurately be measured the variations such as position, displacement of noncontact testee, is mainly used in the measurement of the geometric senses such as the displacement that detects thing, thickness, vibration, distance, diameter.
Laser scanning displacement transducer principle is laser triangulation, and this mensuration generally is applicable to high accuracy, short-range measurement.
The below does simple an introduction to laser triangulation: generating laser is surperficial with red color visible laser directive testee by camera lens, laser through the object reflection passes through the receiver camera lens, received by inner CCD linear camera, according to different distances, the CCD linear camera can " be seen " this luminous point under different angles.According to this angle and known laser and the distance between camera, digital signal processor just can calculate the distance between sensor and testee.
Utilize laser scanning sensor compartment of terrain that the surface of being unearthed is scanned, and the rate signal in conjunction with belt conveyor is processed in processor, can obtain the amount of being unearthed.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
